To all whom it may concern."

Be it known that I, Lrio A. Kirorr, a

citizen'of. the United States, and a resident of Findlay, in the county of Hancock and State of Ohio, have invented a certain new and useful Conveyor Control for Ditching- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and usethe same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification, This invention relates particularly to self adjusting means for the conveyers of. excavating or ditching machines of the rotary t e.

dhe object'of my invention is the provision, in a machine of the character described, of means which is operable to effect an ad- .justment of the conveyer relative to the out ting-wheel and its carrying frame. and which is adapted to automatically maintain the 'conveyer'in any'pr'edetermined position of adjustment relative to the cutting-wheel during a raising or lowering; of the cuttingwheel and its carryingf 'ame.

The invention is fully described in thefollowing specification, and while, in its broader aspect, it is capable'of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying dran 'ings, in which,

Figure 1 is a side elevation of a portion of a ditching machine embodying myinvention, and Fig. 2 is an end elevation of the portion of the machine shown in Fig. 1 lookmovements by the upright frame L -ables 6 control the vertical adjusting movemeiits f the cutter wheel carrying frame 4: in a well known manner. j

A boom 11 project vertically and ou' t'-. wardly from one side of th upright frame 3 over the outer or free enn portion ofthe conveyer frame 7 and is supportedin desired position by rods 12, which extend back from the free end of the boom and are con} A end.

A cable 14, which adjustably supports the free end of the conveyer frame 7, is at tached to" such frame throughhemediurn of a bail 1.5, theme passes upwarid over the sheave l3, thence. forward to the upright frame 3, over a sheave '16 carried thereb thence downward and around a sheave 1;, which is carried. by the framegid near as lower end, thence across l-said j-"frame and" opposite side thereof, thence real around a sheave 19, carried at the -i of the tractor frame 1, thence upwa a sheave 20 carried by the cutting carrying frame 4, and then rearwii and ing' in a conveyer lowering direction by pawl;

A hand controlwheel It is apparent with this arrangementthat, a the position of the conveyer frame 7 rel'a tive to the frame a and cutting-wheel'fican the cable is; It is also apparent that when the conveyer has been once adjusted relative to the cutting wheel, such adjustment is maintained irrespective of the raisingarid', lowering movements of the cuttin wheel frame to have raising and lowering moves 4 at one side thereof and thence extends ments relative to the outer end of the --con-: veyer when an ad ustment of the earning be changed, as desired, by a turning of thg nand controi wheel 22, which will-permit. a lengthening out or cause a taking up of;-

wheel was effected, and necessitating a frequent ad usting of the conveyer frame to maintain it in desired material conveying position.

I 'wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, except in so far as such limitations are specified in Y the claims.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is,-

1. In a machine of the class described, in

combination, a main frame, a cutting-Wheel carrying frame carriedby and vertically adjustable relative to said main frame, a conveyer frame pivotally projecting from said adjustable frame, a drum carried by said adjustable frame, a cable connecting the free end of the conveyer frame and said drum,

and means having parts carried by said and adjustable frame, a cable guided by said sheaves and attached at one end to the free end portion of said conveyer frame to serve to support the same, and means carried by said adjustable frame and having connection with the other end of said cable, said means being operable to take up or pay out the cable.

3.111 a machine of the class described, in combination, a tractor frame having an up right part, a cuttingwvheel frame carried by and vertically adjustable relative to the upright part of said tractor frame, a conmovements, a boom projecting from said adjustable frame for vertical swinging movements, a boom projecting from said upright frame part over the free end portion of said conveyer frame, a cable Winding and control means carried by said adjustable frame, acable connecting the free end portion of said conv'eyer frame and said means and serving to adjustably support said conveyer frame, and guide means for said cable having parts carried by said boom, said tractor frame and its upright part, and saidadjustable frame whereby the adjustable frame may be raised or lowered Without changing the adjusted position of the conveyer frame relative thereto.

In testimony whereof, I have hereunto signed my name to this specification.
